From: Christian Themes in Baha'i Literature
Some Christians claim that the Holy Ghost descended after
the resurrection of the Christ and that Christ is alluding to this. But as the
Holy Ghost was always with …Christ, is this logical? Again he says, "He
will guide you unto truth," “He will be better for you than I”, He adds,
"Until I go, he cannot come." Endeavor to understand the divine
words, otherwise difficulties will arise. Had the Jews understood symbology,
they would have understood the Christ. The holy books are full of significance
and must never be taken literally. Elijah also was expected to come from
heaven, and … Christ said, "Elijah is none other than John the
Baptist." The reality of John was in the supreme concourse. It is
essential to have divine perception in order to see the truth, to hear the
call, and obey -- liberating the hearts from all earthly attachment. (Abdu'l-Baha, Divine Philosophy)
